Hear Rihanna's Comeback Single!
Off her Nov. 23 album Rated R, "Russian Roulette" marks Rihanna's return to the music scene, four months after her ex, Chris Brown, was sentenced to 180 days of community labor for beating her before the 2009 Grammy Awards in February.
In July, Brown, 20, apologized for the incident, telling TMZ he was "ashamed" of his actions.
"I'm not going to sit here and make any excuses," Brown said. "I take great pride in me being able to exercise self-control and what I did was inexcusable. I am very sad and very ashamed of what I've done."
